What the numbers say
Overview
Bareilly's AQI moved from 111 in 2022 to 61 in 2024 — a fall of 45.0% over 2 years. The long-run trend is roughly stable, with a regression slope of 0.0 AQI points per year.
The data story
The worst recorded year in Bareilly was 2022 at AQI 111, while the best was 2024 at AQI 61. The city has posted 3.9% of all measured days above AQI 200 (the Poor threshold), and its worst recorded single day hit 292 on 3 Nov 2022.
Why this pattern
Bareilly's trend has been stable — neither clearly worsening nor clearly improving. That stability often masks underlying growth in emissions being offset by cleaner vehicle technology or weather variability. The NCAP era from 2019 onward is the key policy backdrop; stability here means targets have not yet translated into measurable ground-level change.
What to do with this
For planners and residents, the trend matters as much as today's number. A worsening city needs aggressive source control and personal protection investments like indoor purifiers. An improving city rewards continued policy pressure but still requires caution during peak months. Use the live AQI page for day-to-day decisions and this chart for multi-year context. Year-over-year change of more than 10% in either direction is typically real signal, not noise.
